Identification, quantification and analysis of observable anthropogenic debris along swiss river and lakes (IQASL)

IQAASL is a project sponsored by the Swiss Federal Office for the Environment to quantify shoreline trash along swiss lakes and rivers. Multiple small scale litter surveys are completed at different locations within a designated survey area. For the year 2020/2021 the survey areas were defined by the municipalities that border the Aare, Rhône, Ticino and Linth/Limmat rivers and any lakes or rivers that contribute to one of these rivers.

What is a litter survey?

A litter survey is the identification and count of all anthropogenic objects found within a delimited area, in this study all surveys were bordered on one side by water (a river or lake). Each object is placed into one of 260 categories¹. The location, date, survey dimensions and the total number of objects in each category is noted.

Purpose of the surveys

The survey results help ALL stakeholders identify the items that make up the mass of trash found in the natural environment and where those objects are most likely to be found. The surveys answer the following questions:

  • What items are found?
    • The most abundant objects from the water feature and the survey area sorted by total object count
  • How much is found ? (total weights and item counts)
    • Total object count, total weight and weight of plastics
  • How often are these items found?
    • How often the most abundant items were identified
  • Where do you find the most?
    • Pieces of trash per meter (pcs/m): the ratio of number of objects found to the length of the shoreline for each survey location

These are the most frequently asked questions and should be considered when determining any mitigation or reduction strategies.

Assumptions:

  • The more trash there is on the ground the more a person is likely to find
  • The survey results represent the minimum amount of trash at that site²
  • For each survey: finding one item does not effect the chance of finding another³

Purpose of this report

Summarize the results for the water feature and define the magnitude of those results with respect to the rest of the survey area.

Results: Aare survey area

Scope

The Aare source is the Aare Glaciers in the Bernese Alps of south-central Switzerland. The Aare is the longest river entirely within Switzerland with a length of 295 km and drainage area of 17,779 km2. Following the Aare Gorge, the river expands into the glacial Lake Brienz. The Aare is canalized at Interlaken before entering Lake Thun and exiting through the city of Thun.⁵ The river then flows northwest surrounding the old city center of Bern on three sides. Continuing west to Lake Wohlen Reservoir it turns north to Aarberg and is diverted west into Lake Biel by the Hagneck Canal, one of a series of major water corrections made in the 19th and 20th centuries connecting Neuchatel, Biel and Morat lakes through canalization. From the upper end of Lake Biel, at Nidau, the river exits through the Nidau-Büren Canal/Aare Canal.⁶

The Limmat and Reuss rivers⁷, two major tributaries converge into the Aare at the Limmatspitz between the cities of Brugg and Untersiggenthal in Canton Aargau.⁸ The Aare river ends in the north-western region of Koblenz, Switzerland where it joins the Rhine river which eventually terminates in the North Sea.

The most abundant objects

Combined, the ten most abundant objects found in the Aare survey area represent 65% of all objects found.

Of the most abundant objects in the Aare survey area, 9 are also among the most abundant in All survey areas.

  1. Industrial pellets (nurdles)
  2. Expanded polystyrene
  3. Insulation: includes spray foams and foam board
  4. Cigarette butts and filters
  5. Fragmented plastics
  6. Styrofoam < 5mm
  7. Industrial sheeting
  8. Food wrappers; candy, snack packaging
  9. Glass or ceramic drink bottles, pieces

The most abundant objects: results by water feature

Some objects are found throughout the survey area and some of those objects are found in all survey areas. Knowing which objects are most abundant and what those values are helps idenitify sources or zones of accumulation.

top

How often are these objects found?

Some objects are found often and in elevated quantities, others are found often and in small quantities and some objects are found less often but in large quantities. Knowing the diffference can help find the sources.

The number of surveys where at least one of the most abundant objects were found

Note The survey area results include the results from the current water feature

top

Utility: percent of total objects collected

The utility type is based on the utilisation of the object prior to it being discarded. Objects that are found are placed into to one of the 260 categories. Those categories are grouped according to utilisation.

For example, a piece of plastic could be placed into the category 'Fragmented plastics', depending on its size. However, a piece of plastic that was once a bucket and we know this because we are familiar with either the brand or the product or if we recognize it as a piece of a bucket it is placed in the code for buckets⁸.

  • wastewater: items released from water treatment plants includes items likely toilet flushed
  • micro plastics (< 5mm): fragmented plastic items and pre-production plastic resins
  • infrastructure: items related to construction and maintenance of all infratructure items
  • food and drink: primarily single use plastic items related to consuming food and drinks outdoors
  • agriculture: primarily industrial sheeting includes mulch films
  • tobacco: primarily cigarette ends includes all smoking related material
  • recreation: includes fishing, hunting, boating and beach related objects, excludes food, drink and tobacco items
  • packaging non food and drink: packaging or wrapping material not identified as food, drink nor tobacco related
  • plastic fragments: foam and plastic fragments of indeterminate origin and use
  • personal items: accessories, hygiene and clothing related

⁸ See the annex for the complete list of objects identified, includes category and group classification - the code for a buckets is G57

Effective data

The data is submitted in two parts. If a survey is missing either part we check the paper records and update when possible.top

All the surveys found a home in the dimensional data

All dimensional records found a home in the survey data!

Correlation of results to local conditions

The survey results for the most abundant objects were ranked against population and three other criteria for each survey location. Within a radius of 1500m of each survey location the following characteristics were calculated:

  • buildings: m² of surface area attributed to buildings

  • streets: length in meters of all roads

  • number of stream/river discharge points

The three attributes were evaluated seperately and combined - urbanization. Urbanization is the weighted value of the sum of population, buildings and streets for each survey. The values were evaluated using the Spearmans rank correlation with p= 0.1. The results can be interpreted in the following way:

  • " + " - positive correlation: the chances of finding the object and the quantity found were increased as the amount of the attrubute increased within 1500m the survey area.

  • " - " - negative correlation: neither the chances or the quantity of finding the object found were increased by this attribute, and previously it was found in greater quantities when this atribute was minimized within 1500m of the survey area.

  • " NA " - no effect: there is no statistical basis to reject a null effect by this attribute based on the current results.

Important! Results vary for each location and at each survey. A correlation is not a sign of causation.
